“Weapons of war don’t belong on the streets,” Sen. Dianne Feinstein, D-Calif., said Sunday on Fox News. Feinstein, who became mayor of San Francisco when a gunman assassinated Mayor George Moscone and who authored anti-assault weapon legislation after a mass killing in San Francisco, has been a strong advocate of gun control. In her view, shooters use these weapons because they can get them.
